The Lowdown
Alright, surfers, Rusty here. Let's have a look at what's in store for the next couple of weeks.
We’ve got a bit of a mixed bag coming our way at Jaconé. The week kicks off with some decent energy, but things get a little messy mid-week before a cleaner run of swell towards the end of July and into the start of August.
The first real standout is Monday morning, July 20th. The water is sitting at 71°F which is pretty much average for this time of year. We’ve got a clean 6ft swell from the ENE, a bit short in the period at 7 seconds, but with a light offshore wind from the NNE, it’s going to be clean. The combined energy is moderate (424). This is the best on offer in the early days.
Tuesday morning, July 21st, is also worth a mention. The swell drops a touch to 5ft from the ENE with an 8-second period, but again, that light NNE offshore wind keeps it clean and the energy is still solid (376).
The middle of the week, Wednesday and Thursday, are pretty ordinary. The swell drops right off, and by Thursday the wind turns onshore and messy. It’s a good time to get other things done.
Now, here’s the next real highlight. Saturday morning, July 25th is a beauty. The swell is a clean 4ft from the south with a 9-second period, and we’ve got glassy conditions with a light NW breeze. The energy is moderate (270). This is a prime session for a surfer who wants clean, fun waves.
Sunday, July 26th, has a long-period groundswell (12 seconds) from the south, but it’s blown out by strong onshore winds, so it’s a pass.
After a run of poor conditions, the next real standout is Tuesday morning, July 28th. The swell is smaller at 3ft but it’s from the south with a very long 13-second period, and the wind is glassy from the NNE. The energy is strong (430) for that size. This long-period, glassy south swell will be best on a reef or point, but it’ll be a special morning.
We then get a bit of a lull until Friday afternoon, July 31st. A new 4ft south swell with an 8-second period arrives, and with a light cross-offshore breeze from the ESE, it’s looking clean with moderate energy (241).
The start of August looks promising. Saturday morning, August 1st, has a 4ft swell from the SE with a 7-second period and a light offshore NE wind. Clean and fun. Sunday morning, August 2nd, is a standout with a 4ft, 8-second E swell, a light NNE offshore, and strong energy (433). This is a solid morning for a surf.
Monday morning, August 3rd, has a bigger 5ft E swell with a 7-second period and a light offshore NE wind. The energy is strong (417). This one is getting a bit bigger, so it’s more for intermediate and above surfers, but it’s clean.
We finish the run on Tuesday morning, August 4th, with a clean 3ft ENE swell, a 7-second period, and a gentle offshore from the NE.
So, to sum it up: the best windows are Monday morning the 20th and Saturday morning the 25th for the first week, and then look towards Tuesday morning the 28th for a very glassy, long-period south swell, and Sunday morning, August 2nd, for a solid, clean E swell. Get out there.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
